Description

Technical Field

[0001] This utility model relates to the field of heating, ventilation and air conditioning technology, and in particular to an energy-saving automatic control device for heating, ventilation and air conditioning. Background Technology

[0002] Energy-saving automatic control devices are intelligent equipment that collect environmental parameters in real time through sensors and automatically adjust the operation of HVAC systems according to preset logic by a controller. They can accurately match air conditioning load with actual demand, avoid ineffective energy consumption, and significantly improve energy efficiency. Simultaneously, they can automatically maintain a comfortable indoor environment, reduce manual operation, lower maintenance costs, and provide timely warnings of equipment malfunctions through data monitoring, ensuring stable system operation and achieving multiple goals of energy saving, comfort, and efficient management. Energy-saving automatic control devices typically consist of sensors, controllers, and actuators. During operation, sensors monitor environmental or equipment parameters such as temperature, light intensity, and energy consumption in real time, transmitting the data to the controller. The controller analyzes and processes the data based on preset energy-saving strategies. When parameters deviate from the energy-saving target, it issues commands to drive the actuators, automatically adjusting the equipment's operating status to achieve on-demand energy supply, reduce waste, and ultimately achieve energy savings. In existing technologies, some energy-saving automatic control devices still have fixed installation locations that cannot be changed, making it impossible to ensure that environmental data can be collected in the optimal locations such as areas with high personnel activity and stable airflow. This results in low control accuracy and problems such as controller lag and slow response due to high temperatures. Therefore, an energy-saving automatic control device for HVAC is proposed to solve the above problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0010] A heating, ventilation, and air conditioning energy-saving automatic control device, referring to Figures 1 to 3The system includes a base plate 1, which supports the main structure. A base column 2 is fixedly connected to the top of the base plate 1, which supports the upper structure. A drive mechanism 3 is fixedly connected to the top of the base column 2. The drive mechanism 3 changes the height of the automatic control device by lifting. A housing 4 is fixedly connected to the top of the drive mechanism 3, which supports and protects the internal structure. A heat dissipation mechanism 5 is fixedly connected inside the housing 4, which dissipates heat from the controller 6 to prevent it from overheating and affecting its operation. The controller 6 is fixedly connected inside the housing 4, which controls the HVAC system and changes its operating status. The drive mechanism 3 includes a fixed column 31, which supports and limits the lifting column 32. The bottom of the fixed column 31 is fixedly connected to the top of the bottom column 2. The lifting column 32 is slidably connected inside the fixed column 31. The lifting column 32 drives the outer shell 4 to adjust its height by lifting. A protective box 33 is fixedly connected inside the fixed column 31 to protect the motor 341 from external damage. A support plate 35 is fixedly connected to the top of the bottom column 2 to support and limit the lifting assembly 34. Two telescopic plates 36 are slidably connected inside the lifting column 32 to prevent external dust and moisture from entering and damaging the internal mechanism. The lifting assembly 34 is fixedly connected inside the protective box 33 to drive the lifting column 32 to lift. The lifting assembly 34 includes a motor 341, which drives a rotating rod 342 to rotate. The motor 341 is externally fixedly connected to the inside of the protective box 33. The rotating rod 342 is fixedly connected to the drive end of the motor 341. The rotating rod 342 drives a rotating wheel 343 to rotate. The rotating wheel 343 is externally fixedly connected to the rotating rod 342. The rotating wheel 343 drives a belt 344 to rotate. A connecting block 345 is fixedly connected inside the lifting column 32. The connecting block 345 connects the lifting column 32 and the belt 344 so that it can rise and fall with the rise and fall of the belt 344. The belt 344 is fixedly connected inside the connecting block 345. The belt 344 drives the connecting block 345 to rise and fall. A fixing rod 347 is fixedly connected inside the support plate 35. The fixing rod 347 supports and limits the limiting wheel 346. The limiting wheel 346 is rotatably connected to the outside of the fixing rod 347. The limiting wheel 346 limits the belt 344. Specifically, the outer casing 4 provides a fixed installation space for the heat dissipation mechanism 5, ensuring the orderly operation of heat dissipation. The heat dissipation mechanism 5 is the cooling guarantee for the controller 6, continuously dissipating heat from the controller 6 to prevent problems such as operation stagnation and command errors caused by excessively high operating temperature over a long period of time. This ensures that the controller 6 always maintains a highly efficient and stable working state, providing reliable support for the precise control of the air conditioning system. The fixed column 31 restricts the lifting trajectory through sliding cooperation with the lifting column 32, ensuring a smooth and non-deviational lifting process and ensuring the accuracy of height adjustment. The support plate 35 prevents the lifting assembly 34 from shifting or loosening due to vibration or other reasons during operation. The motor 341 is the starting component for power transmission of the lifting assembly 34. The belt 344 is the key transmission component that converts rotational power into linear lifting power. The connecting block 345 is the bridge for power transmission between the belt 344 and the lifting column 32. The limit wheel 346 prevents the belt 344 from slipping, deviating, or loosening during operation, ensuring efficient and stable power transmission and ensuring the smoothness and accuracy of the lifting column 32's lifting.

[0011] Reference Figures 2 to 4 The heat dissipation mechanism 5 includes multiple louvers 51. The louvers 51 optimize the air convection path, enhance air circulation, and accelerate heat dissipation. The external parts of the multiple louvers 51 are fixedly connected to the inside of the housing 4. A connecting plate 52 is fixedly connected to the inside of one of the louvers 51. The connecting plate 52 fixes the fan 53. The external parts of the connecting plate 52 are fixedly connected to the fan 53. The fan 53 can automatically start and stop according to the temperature to accelerate the internal air circulation. A sensor 54 is fixedly connected to the top of the controller 6. The sensor 54 detects various indicators of the controller 6 and sends corresponding signals to start the other devices. An alarm 55 is fixedly connected to the top of the housing 4. The alarm 55 sounds an alarm to remind maintenance personnel. Specifically, the arrangement of louvers 51 ensures smooth airflow while also preventing dust and other debris from entering the casing 4, thus combining heat dissipation and protection. When the temperature of the controller 6 rises to a set threshold, the fan 53 starts, accelerating the airflow inside the casing 4 and enhancing heat dissipation efficiency. When the temperature drops to a safe range, the fan 53 automatically shuts off, achieving a balance between energy saving and heat dissipation. The sensor 54 monitors various operating indicators of the controller 6 in real time. Once an abnormality is detected, it immediately sends a corresponding signal, activating the fan 53 and other related devices for adjustment. If the abnormality exceeds the adjustment range, it will also trigger a subsequent alarm mechanism, providing early warning for the safe operation of the device. When the sensor 54 detects a serious abnormality in the controller 6 that cannot be resolved by its own adjustment, the alarm 55 will emit audible and visual alarm signals to promptly remind maintenance personnel to inspect and handle the situation, preventing the fault from escalating and causing the device to shut down or be damaged, and ensuring the continuous and stable operation of the device.

[0012] Reference Figures 2 to 4The bottom of the protective box 33 is fixedly connected to the top of the base column 2, the bottom of the motor 341 is fixedly connected to the top of the base column 2, the inside of the belt 344 is rotatably connected to the outside of the wheel 343, the other end of the belt 344 is rotatably connected to the outside of the limit wheel 346, the other end of the rotating rod 342 is rotatably connected to the inside of the support plate 35, the other end of the fixing rod 347 is rotatably connected to the inside of the fixing column 31, the bottom of the connecting plate 52 is fixedly connected to the inside of the outer shell 4, and the bottom of the fan 53 is fixedly connected to the inside of the outer shell 4. Specifically, the connection between the protective box 33 and the base column 2 can stably transfer the weight of the protective box 33 and its internal components to the base plate 1, preventing the protective box 33 from shifting or shaking due to vibration or other factors during device operation. The connection between the belt 344, the rotating wheel 343, and the limiting wheel 346 forms a complete power transmission path, enabling the rotational power of the rotating wheel 343 to be efficiently transmitted to the limiting wheel 346 through the belt 344, ensuring flexibility in the power transmission process and reducing energy loss.

[0013] The implementation principle of this application embodiment is as follows: When the staff needs to maintain the device, the motor 341 can be started to drive the rotating rod 342 to rotate, thereby the rotating rod 342 drives the rotating wheel 343 to rotate, thereby the rotating wheel 343 drives the belt 344 to rotate, thereby the belt 344 drives the connecting block 345 to rise and fall, thereby the connecting block 345 drives the lifting column 32 to rise and fall, thereby the lifting column 32 drives the outer casing 4 to rise and fall, thereby the outer casing 4 drives the controller 6 to rise and fall, and synchronously drives the sensor 54 to rise and fall, thereby achieving the effect of adjusting the height of the automatic control device. It can flexibly adapt to the spatial height requirements of different installation scenarios, facilitates precise adjustment of the device height according to the optimal monitoring position of the sensor, ensures more accurate environmental parameter collection, facilitates quick raising and lowering of the device during later maintenance, reduces the difficulty of disassembly and repair, improves installation and maintenance efficiency, and indirectly ensures the stable operation of the system and the full realization of energy-saving effects.

[0014] Under normal conditions, the automatic control device optimizes the air convection path through multiple louvers 51 to enhance air circulation and accelerate the dissipation of heat inside the device. When the internal temperature is detected to be too high, the fan 53 is automatically activated to further accelerate the internal air circulation and enhance heat dissipation. This achieves the effect of accelerating the internal air circulation and enhancing the heat dissipation of the internal structure, avoiding problems such as sluggish operation and slow response due to high temperature. It ensures the stable operation of core components such as sensors and controllers 6 and extends the service life of the equipment. In addition, the sensor 54 monitors various indicators in real time. Once an abnormality is detected, it sends a corresponding signal to activate other related devices. If the situation requires handling, the alarm 55 on the top of the casing 4 will sound an alarm to promptly remind maintenance personnel to carry out maintenance.
